Hey guy's, I'm now considering moving up to 380cc injectors as I have an Alta intake, 15% pulley, Milltek catback and a JCW software upgrade , the JCW software is what's prompting the injector upgrade. Here's the list of three I've found if someone can recommend others thats great, if you own or have experience with any of these I'd appreciate the feedback:

1. JCW factory 380cc injectors
2. Helix High flow 380cc
3. Madness high flow 380cc's ( way more money for some reason?)

From the reading I've done the Helix high flows sound apealing with their twin cone pattern!

 

I have the Helix in my JCW. The Helix's make what feels like more power.

 

JCW or the Helix. Both have proper spray pattern. Talk to Eric.

 

Thanks funny you should say that, I sent him an email earlier today

 

For those interested:email from Eric: "The only difference in the injectors is the Manufacturer and the price. The performance is exactly equal: we just found a more economical solution. Please don't hesitate to call if you want to discuss."

 

Eric is a great guy and really knows his stuff. Great customer relations.

 

I had a set of Helix injectors and they required spacers on the fuel rail to stop them going in too far. This caused clearence issues when trying to fit the intercooler boot clamps. Recently replaced with JCW, much happier.

 

I'd call Eric to see if thats true. First time I heard about that.

 

I have no first hand experience with Helix and I have heard absolutely nothing but good about them, but the JCW injectors are only $7.50 more per injector than the Helix/bosch brand....seems worth it to me for the JCW part...

 

My thoughts also. If it was me I'd get the JCW.

 

Thanks for the info, I've sent this off to Eric, and we'll see what he says.......

Update:
Wow that was fast, Eric was on this! here's his reply: " This was a prototype injector that we discontinued. It's completely different from the one we offer now."

 

Eric is a great guy. He takes care of his business and his customers. Save some $ and get the Helix injectors.

 

On the subject of injectors, with the 15% pulley, CAI, and after market exhaust, how much worse would MPG be if you got 380cc injectors? Driving style: All accelerating done in first and second gear, 90% throttle. I could care less about MPG and money spent on gas, I'm just curious how the injectors would effect it. You have to prioritize your life man, in mine, car comes first. Live like a pauper and divert all spare money to the car.

 

I'd say I lost about 2 mpg, from around 27 to 25 when I added the JCW injectors. I might get some of this back with an ECU tune, though.

 

I did'nt know that WOW

 

Why run such SMALL injectors!!! customminishop.com sells 400cc and possibly 440cc injectors... Have some fun.... They are produced from factory injector bodies.

 

Because dumping more fuel than needed doesn't make it run better infact it will run worse

 

How do you know for sure that you only need a 380cc injector? Never plan on upgrading the car any further? Trust me, it sucks buying a second set of injectors, because you opted for a smaller set in the beginning. Any programming will eliminate the over fueling problem, but you'd rather run a hair rich than lean at 6500 rpm!!!!

 

I got JCW injectors and I am very satisfied with them.

I got them from Helix.

 

I have been reading this thread for a while trying to decide on injectors for my r53. I reached out to Madness Motorworks because a bunch of people recommended them. After calling multiple times (yes I left a voicemail) and emailing. I was able to talk to someone on their online chat service. The guy/girl knew nothing about any of the products even when I asked very basic questions. I asked who would know and was told to just buy the injectors as they were "the right ones". I tried my best to be polite but was pretty annoyed by the end.
I would maybe stay away from their online purchases unless you guys can get someone on the phone to confirm specifications. (I will add the last of my interactions with the rep below) @md
